Abstract
Systems and methods for processing an index are described. To insure that the most updated index is available without having to update the index after every change (which can consume enormous resources), a specially marked postings list is generated for a changed item. During retrieval, the specially marked postings list supplements the existing content of an inverted index referencing the changed item. In this manner, the retrieval result for items containing the term under which the changed item was originally indexed is updated in accordance with the specially marked postings list to insure the most accurate retrieval result.
